the generator set from the load by
opening the line circuit breaker or by
disconnecting the generator set output
leads from the transfer switch and
heavily taping the ends of the leads.
High voltage transferred to the load
during testing may cause personal
injury and equipment damage. Do not
use the safeguard circuit breaker in
place of the line circuit breaker. The
safeguard circuit breaker does not
disconnect the generator set from the
